使用數據庫服務自動配置在IBM / Bluemix上啟動Java應用程序時出錯

Question

我在java上有一個使用jpa（spring-data）的應用程序，並且我在cf：push的bluemix上進行了構建，一切正常..但是當應用程序開始開始時拋出該錯誤：

[INFO    ] Auto-reconfiguring beans of type javax.sql.DataSource
Failed to created cloud datasource for ubivisDB service
[INFO    ] FFDC1015I: An FFDC Incident has been created: "org.cloudfoundry.reconfiguration.org.springframework.cloud.service.ServiceConnectorCreationException: Failed to created cloud datasource for ubivisDB service com.ibm.ws.webcontainer.webapp.WebApp.notifyServletContextCreated 1341" at ffdc_15.08.28_19.03.47.0.log

當我看到服務是否與cf：services綁定在應用程序上時：

 mvn -P bluemix cf:services

我認為可能是bluemix更新自動配置...任何想法嗎？ ps：以前我可以毫無問題地運行，但是現在我不能...

經過幾天沒有任何變化，我發起了一場新的戰爭...現在出現了一個錯誤

當綁定了公認的關系數據庫服務（DB2，mysql等）時，Liberty buildpack會自動配置數據源。 JNDI名稱將為“ jdbc /”。 因此，您可以使用該JNDI名稱在代碼或JPA配置/批注中查找數據源。 在Liberty buildpack中閱讀有關此自動配置功能的更多信息： https ://www.ng.bluemix.net/docs/starters/liberty/index.html#automaticconfigurationofboundservices
